Referring to Figures 1 to 9 inclusive, the numeral 1 designates the body portion of the device which comprises a rear section 2 and top and bottom sections 3 and 4'. The top section 3 and bottom section 4 are provided coins to be inserted in the individual stacks.

Each. opening 5 is disposed in axial alinement wlththe corresponding opening 6. A plurality of rods 7 is mounted adjacent each set of openings 5 and 6, and have their ends reduced for insertion within openings 8 in the top and bottom sections 3 and 4 oi the body portion. The rods 7 are preferably formed of polished steel, and their inner faces are flush with the faces of the openings 5 and 6. The rods 7 are arranged insets and the rods of each set are preferably equidistant-1y spaced and are adapted to contain coin stacks 9 therebetween.

Mounted below the body portion 1 is a coin chute 10 which slopes downwardly toward one end oi the machine, as shown in Figure 2. Thechute has a front section 11 prefeu ably formed integral therewith, the front section being provided with openings 12 for the reception of downturned lips 13 formed on the front of the bottom section 4 of the body portion 1. The chute 10 also has a rear section 14, secured to the rear wall 2 of the body portion in any suitable manner such as b rivets or thelike. The rear section 14 pro erably extends upwardly the greater portion of the height of the rear wall 2 of the body portion, so that the connection between the body portion and the chute is extremely rigid. The reduced end of the chute is closed by an end plate 15, while the opposite end is provided with an end plate 16. The end plates 15 and 16 may be secured to the front and rear walls of the chute by any suitable means, such as lips 17' Figure 5. The lower end of the plate 16 is-spaced from the bottom of the chute, as shown in Figure 2, to provide a space for the passage of the coins. The lower end of the bottom of the chute extends slightly beyond the walls thereof and is downturned to form a lip 17 for a purpose to be described.

.A pair of bearing rods 18 preferably formed of polished steel is mounted below the bottom section 4 of the body portion and on opposite sides of the openings 6. These rods are mounted longitudinally of the deviceand have their ends secured to the end plates15 and 16.

Mounted below each of the openings 6, is

a slidable. coin cutting member 1.9. The

members 19 are preferably formed of sheet metal and are provided substantially centrally thereof with openings 20 correspond ing in size to the coins in the individual stacks. In the normal position of the slidable members of the device,. the openings 20 are inregistration with the openings 6.

Dependinghps 21ers formed on opposite sides of the ends of the memberslQ, and are provided with openings 22 Figure 9 to receive the bearing rods 18. A )lurality of depending lips- 23 is provided a jacent each of the openings -20, andhavetheir inner faces flush therew th, The length of the lips .37 and 38 are 23 varies according to the number of coins to be cut from each coin stack. As clearly shown in Figures 2 and 6, the members 19 contact through the entire length of the machine, for a purpose to be described. Coil springs 21 are mounted in one end 01 the device and surround the rods 18 adjacent the ends thereof. As shown in Figure 2, these springs are arranged between the end plate 15 and the adjacent lips 21 of the coin cutting members 19. It will be obvious that the springs 2 1, acting against the end lips 21, will move all of the coin cutting members 19 to their outermost position, since the members 19 are in contact throughout the length of the machine.

Actuating members 25 are provided, each of which embodies parallel arms 26. The arms 26, at points spaced from their ends, are provided with shoulders 27 for a purpose to be described. The outer ends of the arms 26 are connected by cross pieces 28 which form operating keys. 'The actuating members 25 preferably converge upwardly and the inner ends oi the individual arms 26 terminate in upturned lipsv 29, which are provided with openings adapted to receive the bearing rods 18.. Each pair of lips 29 preferably contact with one pair 01 lips 21 of the coin cutting members. The end plate 1.6 is provided withv openings 3lythrough which the outer ends of the arms 26 extend. The shoulders 27 are adapted to contact with the inner face of the plate 16, as shown in Figure 5 to limit the outward movement of the members 19.

Coin stack supporting members 32 are mounted beneath the openings 6 and 20. Each of the members 32 consists of a body portion 33 provided with'a cutout portion The cutout portions 34.- are arcuate in shape and so arranged that they will be in axial alinement with the openings 20 when the coincutting members 19 are shifted to their innermost positions. Several of the members 32 have their ends turned downwardly and outwardly as shown in Figure 4 to provide clearance for the lips 21 of coin cutting members.

In order that the device may properly function, it is desirable that the coins properly seat on one another within the stacks 9 and we have accordingly provided a clutch member 3:3 bent on a line 36 adapted to seat upon the tops of the individual coin stacks. The rear end of the member 35 is provided with an opening 37 for the reception of the rear rod 7. while the forward end flares outwardly as shown in Figure 7, and is provided with openings 38 for the reception of the front rods 7 The openings preferably elongated. The bend 36 is preferably located rearwardly of the center of the coin stack and the forward end of the member slopes uynvardl more than the rear end thereof, so that the openings 38 are above the openings 37. Thus it will be seen that the distance between the openings 38 and the opening 37 is greater than the horizontal distance between the front rods 7 and the rear rod 7. If the coins in the stack 9 partake of any movement, due to the jolting or jarring of the device, the coins, contacting the member 35 at the bend, will raise the rear portion of the clutch member 35 so that the inner ends of the openings 38 and'37 will grip against the rods 7 and prevent the coins from turning up on end or otherwise becoming unseated with respect .to each other. As coins are cut from the bottom of the stack, the rear end of the member drops first, due to the contact line 36 being disposed rearwardly of the center of the coins, and the elongation of the openings 37 and 38 permits the tilting downwardly of the rear end of the clutch member, so that it will slide downwardly about the rods '7 and maintain contact with the uppermost coin of the stack. Instead of inserting coins singly from the top of the stack, as in the present .form of coin holders in use, a plurality of coins may be inserted beneath the clutch member and between the front rods 7 by tilting the coins slightly and pushing inwardly against the member The elongation of the openings 37 and 38 permits the raising of the front portion of the clutch member In Figures 10 and 11, we have illustrated a modified form of clutch member which may be used in place of the member 3:). This form of clutch comprises an upper substantially horizontal triangular portion 39 and a. lower curved portion 40, bent as shown in Figure 10. The portion i0 engages the top of the coin stack rearwardly 'of the center thereof. as does the bend 36 of the clutch member 35. The outer edges of the upper portion 39 are adapted to loosely contact with the front rods 7, while the rear end thereof is provided with an elongated opening 41 to slidably receive the rear rod '7. An opening a2 is provided approximately centrally of the member 39 to receive the forward end 4-3 of a locking key. lip is formed on the forward end of the locking key which seats upon the upper face of the member 39. The inner end of the locking key is curved as shown andv extends through the forward portion of the opennig 41. The end 45 has a shoulder 4.6 contacting with the upper face of the portion 39. The inner edge 17 of the end normally slid-ably contacts with the inner rod 7. The distance between the inner edge '13 of the opening 40 and the curve i9 is greater than the horizontal distance between the edge QS and the rear rod 7'. Thus it will be seen that ifthe upper coin of the stack may be regulated. of coin stack supporting means is employed,

stack is disturbed, it will jar the lower end 10 of the clutch causing the end 43 of the key to rise so that the rear end. 15 of the key acts as a clutch to grip the rear rod 7 to prevent further raising of the clutch member and'hence prevent the unseating of the coins.

In Figures 12, 13, and lat, we have illustrated a modified form of coin stack supporting means whereby the number of coins to be cut from the stack can be regulated as desired. A horizontal member 50 is previded, arranged transversely of the walls of the chute as shown in Figure 13. The member 50 is provided upon its ends with lips 51 adapted to extend through openings in the walls of the chute whereby it may be secured in position. A coin supporting member 52 isprovided having an arcuate cutout portion 53 similar to the cutout portion 34 of the members 32. A pair of depending arms 54 is arranged on opposite sides of the member 52,'and these are provided with slots for the reception of the horizontal member 50. The member 52 is preferably formed of resilient metal so that the arms 154 may be spread apart to permit the insertion of the member 50 within any of the slots55, whereby the number of coins cut from the bottom of the When this form we preferably provide the coin cuttingmember 19 with upturned lips 56 for the reception of the bearing 'rods18, openings being cut in the plate 19 whereby the ends 29 of theiactuating members 25 may extend through the plate 19 to receive the rods 18. In Figures 15 to 21'inclusive, we have illustrated a modified form of the device" wherein we employ solid substantially inverted U-shaped coin containing 'memb'ers 57 carried by the body portion 58. of the device. In this form of the device, thebody portion and the chuteare preferably formedof a single sheet of metal as shown in Figure 18, the upper end being bent outwardly to form a top 59-provided with a coin slot 60, the lower end of the body portion being bent. outwardly toform a chute G1. and upwardly to form a front portion 62. The front portion 62 is'bentback upon itself at '63 and across the machine to form a base plate 64." The base plate is also bent-to (37, the height of which depends upon the number of coins to be cut. from the stack. The front and rear edges of the members 66 are downturned to form flanges 68 adapted to be slidably mounted-within the channels 65. 1

(k5 shown in Figure 1, the members 66 are provided with preferably integral actuating mei'nbere (if) extending toward the outlet end of the chute and provided with keys 70. The keys 70 may be stamped with numbers indicating the amount ot' change to be obtained by pres.--:ing the individual keys.

Transverse edges of the members 66 contact throu hout the lengthof the machine. A spring ('1 Figure 16 is mounted upon the base plate 64. and" contacts with the outer edge of the adjacent coin cutting member 66 to normally move all of the members 66 to the outermost position, so that the openings 67 register with the coins within the containing members 57.

Lips 72 Figures 16 and 18 are stamped out of the body portion to :t'orm guides for the members 69, one of these lips, as at 73, serving as a stop to limit the outward movement of the coin cuttingmembers 66. In Figures 22 and 23, we have illustrated a still further modification of the device in which we employ a series of contacting pivoted coin cutting members 7st, pivoted as at 75 to the base plate 76, A spring '77, mounted upon the base plate 76, serves to maintain the members 7-1 in the normal position be neath the coin containing members, and a pin 78, mounted in the opposite end of the base plate, serves to limit the movement of the members 74. Several Oil" the members 74 are provided with upstanding flanges 79, the height of which depends upon the number of coins to be cut from the stacks. The base plate 76 is provided with openings 80, offset with respect to theopenings in the member 74when the latter are in the normal position.

Lips 80 are formed on the forward edge of the base plate 76 and a second set of lips Sol are formed upon the members 74, corre sponding lips 80 and 81 being normally offset from each other. l l

A chute 82 is mounted below the base plate 76.to direct the coins toward thecenter of the device so that they may be caught in one hand. l

The operation of our device is as follows:

In operating the form of our invention shown in Figures 1 to 10 inclusive, the fingers of the operator are placedbeneath the lip 17 and the thumbplaced in contact with one of the keys 28, depending-upon the amount of change desired, According to the present showing of the device, depression of the lower key 28 cuts live pennies from the lower end of the stack farthest to the right. Depression of the second key 28 from the bottom, actuates the second coin cutting member from the right, which cuts one nickel from this stack, the first coin cutting member being actuated by contact with the second coin cutting mem er to "cut off five pennies, change for a dime being thnsobtaincd. Movement of any one oi? the coin cutting members actuates e ery coin cutting member to the right thereot. Thusit the uppermostkey 28 is pressed, two twenty-live cent pieces will be cut from the first stack on the left, one twenty-five cent piece from the second stack, three nickels from the third stack, one nickel from the fourth stack, and five pennies from theiifth stack. Thus it will be seen that depression of the uppermost key may deliver change for one dollar, the second key change for halt dollar, the third key change for a quarter, the fourth key change for a dime, and the fifth key change for a nickel. It will be obvious that the device may be made to deliver whati-rxcr combination cl coins may be desirable. When the coins are cut by the movement oi the cutting members 19, they are moved to the right until they come into registration with the cutout portions 34; of the supporting members 32, whereupon they will drop into the chute 10 and be directed outwardly into the hand of the operator, without the operator removing his hand from the operating position.

The first modification oil the device operates in a manner similar to that described, while in the form-shown in Figures 22 and 28, the operators thumb is placed on the outside of the lip 81 and his forefinger on the opposite side ot'the lip 80. A slight gripping action of the thumb and torefinger will cut the coins from the bottom of the stack, dropping them through the opening 80 whereupon they will be delivered through the opening in the bottom of the coin chute 82. Operation of any oi? the lips 80 and 81 operates all of the coin cutting members to one side thereof, due to the contacting of the edges oithe coin cutting member.

If desired; the coin cutting member i 01 the penny containers of either form oi: the

device may be arranged to deliver three pennies, so that a. news boy may deliver change to a customer with the price of a newspaper deducted. i It is to be understood that while we have described, the preferred embodiments of our invention, various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
